1. A patient with chronic hepatitis C develops cirrhosis. The formation of
regenerative nodules in the liver represents which type of cellular adaptation?
• A) Hypertrophy
• B) Hyperplasia
• C) Metaplasia
• D) Dysplasia
Verified answer: B) Hyperplasia
Rationale: The liver regenerates via hepatocyte division (hyperplasia) to compensate
for cell death. Hypertrophy is an increase in cell size (e.g., muscle growth), metaplasia
is a change in cell type, and dysplasia is disordered growth (pre-cancerous).
2. A 68-year-old man dies 3 days after a massive myocardial infarction. Autopsy
of the heart tissue would most likely show which type of necrosis?
• A) Coagulative necrosis
• B) Liquefactive necrosis
• C) Caseous necrosis
• D) Fat necrosis
Verified answer: A) Coagulative necrosis
Rationale: Coagulative necrosis is the hallmark of ischemic cell death in solid organs
,(heart, kidney, liver) due to hypoxia. Liquefactive necrosis occurs in the brain; caseous
is seen in TB; fat necrosis is seen in acute pancreatitis or breast trauma.
3. A child diagnosed with Severe Combined Immunodeficiency (SCID) must live
in a sterile environment. This disorder is classified as:
• A) A secondary immunodeficiency
• B) A type II hypersensitivity reaction
• C) A primary immunodeficiency
• D) An alloimmune disorder
Verified answer: C) A primary immunodeficiency
Rationale: SCID is a congenital, genetic defect in T-cell and B-cell development
(primary). Secondary immunodeficiencies are acquired (e.g., HIV, malnutrition).
4. A patient experiences anaphylaxis after eating peanuts. This severe reaction
is triggered by which immunoglobulin binding to mast cells?
• A) IgG
• B) IgM
• C) IgA
• D) IgE
Verified answer: D) IgE
Rationale: Type I hypersensitivity (anaphylaxis) is mediated by IgE cross-linking on
mast cells, causing massive histamine release.
5. A patient develops a blistering, itchy rash on their arm 48 hours after
touching poison ivy. This is an example of:
• A) Type I hypersensitivity
• B) Type II hypersensitivity
• C) Type III hypersensitivity
• D) Type IV hypersensitivity
,Verified answer: D) Type IV hypersensitivity
Rationale: Poison ivy is a classic Type IV (delayed-type) hypersensitivity, mediated by
sensitized T-cells, not antibodies. The reaction peaks in 24-72 hours.
6. A patient with end-stage renal disease receives a kidney transplant. Three
months later, the transplanted kidney shows T-cell infiltration and acute
rejection. This process is defined as:
• A) Autoimmunity
• B) Alloimmunity
• C) Immunosuppression
• D) Immunodeficiency
Verified answer: B) Alloimmunity
Rationale: Alloimmunity is the immune response against antigens from another
individual of the same species (the donor kidney). Autoimmunity is
against self tissues.
7. A patient with mitral valve stenosis is at highest risk for which secondary
hemodynamic complication?
• A) Increased left ventricular afterload
• B) Decreased left atrial pressure
• C) Pulmonary hypertension and right heart failure
• D) Decreased pulmonary capillary wedge pressure
Verified answer: C) Pulmonary hypertension and right heart failure
Rationale: Mitral stenosis blocks flow from the left atrium to the left ventricle,
backing blood into the pulmonary vasculature, causing pulmonary hypertension and
eventually right-sided heart failure.
8. A patient with chronic heart failure has an elevated BNP (B-type Natriuretic
Peptide). This lab value is directly released in response to:
• A) Low cardiac output stimulating the kidneys
• B) Ventricular wall stretch and volume overload
, • C) Hepatic congestion and ascites
• D) Systemic vasoconstriction
Verified answer: B) Ventricular wall stretch and volume overload
Rationale: BNP is secreted by ventricular myocytes in response to increased wall
tension (stretch). It is a compensatory mechanism to promote vasodilation and
diuresis.
9. A patient with severe COPD has a PaCO2 of 68 mmHg and a chronic hypoxic
drive. In this patient, the primary stimulus to breathe is:
• A) High CO2 levels stimulating the medulla
• B) Low O2 levels stimulating peripheral chemoreceptors
• C) High H+ ion concentration in the CSF
• D) Low pH in the blood stimulating the aortic body
Verified answer: B) Low O2 levels stimulating peripheral chemoreceptors
Rationale: In chronic CO2 retainers, the medulla (central chemoreceptors) becomes
desensitized to CO2. The hypoxic drive (peripheral chemoreceptors in the
carotid/aortic bodies) becomes the primary trigger to breathe.
10. A patient is diagnosed with a pulmonary embolism. Which V/Q (ventilation-
perfusion) mismatch is most likely present?
• A) Low V/Q ratio (shunt)
• B) High V/Q ratio (alveolar dead space)
• C) Silent unit (no ventilation, no perfusion)
• D) Normal V/Q ratio
Verified answer: B) High V/Q ratio (alveolar dead space)
Rationale: A PE blocks pulmonary blood flow to a lung segment. Ventilation
continues, but perfusion stops, creating "dead space" (high V/Q). A low V/Q (shunt)
occurs in pneumonia or atelectasis.
11. The primary pathophysiological defect in Gastroesophageal Reflux Disease
(GERD) is:
